c34d6d1162 Python: Add query to handle SQLAlchemy TextClause Injection 
instead of doing this via taint-steps. See description in code/tests.

81dbe36e99 Python: Promote SQLAlchemy modeling 
Due to the split between `src/` and `lib/`, I was not really able to do
the next step without having moved the SQLAlchemy modeling over to be in
`lib/` as well.

ba99e21875 Python: Remove modeling of sqlescapy PyPI package 
I've never seen this being used in real code, and this library doesn't
have a lot of traction, so I would rather not commit to supporting it
(which includes verifying that it actually makes things safe).

Personally I don't think this is the right approach for avoiding SQL
injection either.

5bff5188ac Python: switch from negative to positive list 
This should avoid potentially terrible performance.
Also noted the missing syntactic constructs,
as I went through the documnetation.

605bd19306 Python: Add CWE-328 to py/weak-sensitive-data-hashing 
Reading over the description at https://cwe.mitre.org/data/definitions/328.html:

> The product uses a hashing algorithm that produces a hash value that can be used to determine the original input, or to find an input that can produce the same hash, more efficiently than brute force techniques.

For the data that does not require computationally expensive hashing, that will be the exactly problems that this query finds 👍 (that is, MD5, SHA1)

e865a290de Python: straight port of query 
The old query uses `pointsTo` to limit the sinks
to methods on lists and dictionaries.
That constraint is omitted here which could hurt performance.

af91a2df00 Python: Prevent explosion in poly-ReDoS query 
I consider this to be a short-term solution to the performance problems
we identified. The choice of "at most ten occurrences of `.*`" is
somewhat arbitrary, and it's possible a higher limit would work just as
well.

badf6311c9 Python: Remove flow between globals... 
... in a local scope. Or rather, remove these from the `hasLocalSource`
relation.

This prevents a quadratic blowup when the same global is mentioned
_a lot_ of times within a single function scope.
